High Fermi velocities and small cyclotron masses in LaAlGe
Zhixiang Hu, Qianheng Du, Yu Liu +2
We report quantum oscillation measurements of LaAlGe, a Lorentz-violating type-II Weyl semimetal with tilted Weyl cones. Very small quasiparticle masses and very high Fermi velocit…
Low-Temperature Thermopower in CoSbS
Qianheng Du, Milinda Abeykoon, Yu Liu +2
We report giant thermopower S = 2.5 mV/K in CoSbS single crystals, a material that shows strong high-temperature thermoelectric performance when doped with Ni or Se. Changes of low…
Suppression of Superconductivity and Nematic Order in FeSeS (01, 0.1) Crystals by Anion Height Disorder
Aifeng Wang, Ana Milosavljevic, A. M. Milinda Abeykoon +10
Connections between crystal chemistry and critical temperature have been in the focus of superconductivity, one of the most widely studied phenomena in physics, chemistry and…
Vacancy defect control of colossal thermopower in FeSb2
Qianheng Du, Lijun Wu, Huibo Cao +9
Iron diantimonide is a material with the highest known thermoelectric power. By combining scanning transmission electron microscope study with electronic transport neutron, X-ray s…
Surface Conductivity in Antiferromagnetic Semiconductor CrSb
Qianheng Du, Huixia Fu, Junzhang Ma +4
The contribution of bulk and surface to the electrical resistance along crystallographic \textit{b}- and \textit{c}-axes as a function of crystal thickness gives evidence for a tem…
Room-Temperature Skyrmion Thermopower in Fe3Sn2
Qianheng Du, Myung-Geun Han, Yu Liu +3
We present first room-temperature thermoelectric signature of the skyrmion lattice. This was observed in Fe3Sn2, a Kagome Dirac crystal with massive Dirac fermions that features hi…
